Doctor's Wife was fantastic. At times it was a little dark which made it even better. Him getting killed by the space suit bothers me because I want to know WTH happened and who it was. Won't be getting satisfaction on that front any time soon I suppose.

Given the TARDIS's statement that "The only water in the forest is a River" I'm thinking the person in the space suite is River. Someone might travel back in time to the Forest of the Dead and put River's "program" in the suit. Since the Silence was also mentioned in the title of the Library episode, perhaps they are responsible for getting her in there. Plus we know she gets arrested for killing a good man at some point. As theories go, it's a bit out there, but if the Library episodes don't come into play Moffat will be the king of red herrings in my book.

Also, when River dies she was in a Space Suit, and both those episodes in the Library were penned by Moffet... So who knows.
